IMPROVEMENT IN TOOL-STOCKS FOR DENTAL ENGINES.

Specification forming part of Letters Patent No. 193,429, dated July 24,1877 application filed May 28, 1877.

To all whom it may concern:

Be it known that I, EDWIN TELLE, of New Orleans, in the parish ofOrleans and State of Louisiana, have invented a new and usefulImprovement in Flexible Stocks for Dental Engines, of which thefollowing is a specification:

Figure 1 is a side view of one of my flexible stocks, partly in sectionto show the construction. Fig. 2 shows a modification of the same,partly in sectionto show the construction.

Similar letters of reference indicate corresponding parts.

The invention will first be described in connection with the drawing,and then pointed out in the claim.

A represents the stock, which is formed by coiling a wire spirally andthen coiling another wire spirally around it in the other direction.

This construction makes the stock flexible, and prevents the wires fromuncoiling when 1n use.

The stock A may be made of steel or other suitable metal, may be made ofany desired flexibility, and may be made flexible for their entirelength, as shown in Fig. 1, or may be made partly flexible and partlysolid, as shown in Fig.2, as may be desired. and as a greater or lessdegree of flexibility may be required.

With this construction the various operations of smoothing roughsurfaces upon teeth, and of shaping, smoothing, and polishingcomplicated gold filling, will be much more pleasant to the patient thanwhen said operations are performed .with the wheels, disks, and pointsmounted upon rigid stocks, and there will be much less liability tobreak thin and delicate corunduin disks.

Having thus described my invention, I claim as new and desire to secureby Letters Patent A dental tool-stock made up of the solid part forentering the chuck and the coiled-wire part, upon which the rotatingtool is directly fastened, as shown and described. 1

EDWIN TELLE.
